Han Sen's attitude had fanned the flames of the spirits' hatred towards humans, whom most already despised. The four that had leaped forward to take him on all rushed forward to end him with one mighty, co-operative strike.
A suffocating pillar of black smoke, a hefty boulder, a tornado composed of lethal winds, and a barrage of thin metal spikes all came towards Han Sen, ready to utterly destroy him.
Han Sen was unable to turn back, since he had already committed to the fight and acted all pompous about it. Even if he did seek to flee, there'd be nowhere he could go, anyway.
But he knew he had to act swiftly and carefully. Taking on four emperors solo was no joke, and although those ahead of him weren't a pre-composed team, they seemed to immediately meld together and co-operate well. Undoubtedly, they had been unified through the same desire of wanting to see the human squirm.
